Re: '76 Bronco C-4 Rebuild
Thanks for the reply.
Since the original was working well except for taking time to go from neutral to drive or neutral to reverse, and all the internals looked like new, the bottom of the pan and fluid completely clean, I figured that it was mainly a seal problem.
I don't remember clutch clearances (which I now regret).
I used the new modulator that came with the rebuild kit-green stripe, and tried turning the adjustment both ways with no real change.
I tried putting back the original one with same result as the new one.
I used the original pin don't know length.
Have no idea about preload on pin, repair manual (Haynes) didn't mention it. I don't remember any spring going in before modulator spool valve,
Checked vacuum at modulator - same as manifold around 18 lbs at idle.
Don't remember end float but was careful to put thrust washers and shims in their original
Yes clutch drum piston seals were replaced.
Did air test with good results.
Just carefully cleaned valve body with no changes.
Would putting in spool valve backwards affect both 1-2 and 2-3 shift?
